a stunning loch


This large and bottomless lake is a natural glacial water dammed for water supply.

The lake holds wild brown trout and has a healthy population of arctic char, which have colonised the lake from a re-location project in the catchment.

The start of the access road is very step and winding. Our camper van nearly didn’t make it and probably wouldn’t have if it had been wet.
You can drive nearly all the way to the lake. There’s a locked gate which stops people driving up to the dam.

We fished in April, which is too early for a deep glacial lake.
It was sunny and there was no wind.
There were plenty of small fish rising to midge in the middle.
The water is crystal clear so you’ll need a decent wind and some cloud cover.

We’ll be returning to see if the lake fishes better once it’s warmed up in the summer.
